The ball-shaped head of one bones fits into the cup-like depression of another bone. Allos multi-axial movement. (i.e movemnt in all directions) EX: shoulders joint and hip joint.
Saddle joints (synoval)
the articulationg suface of one bone is concave (saddle-shapped) amd tje reciprocal suface of the other bone is convex. Allows sice to sice and back and forth movement. EX: Metacarpal of thumb and trapezium of wrist
Ellipsoidal or Condyloid joints (synoval)
The oval condyle of one bones fits in to the ellipsoidal depression in anther bone. Allos bi-axial movment (two way) from side to side or back and forth.
EX: Radius and carpals(wrist). Metacarpals and phalanges (knuckles), occiptal condyle and atlas
Pivot joints (Synoval joints)
The rounded or conical suface of one bone that articulates with a shallow depression or foramen of another bone to allow movement in one plane. EX: atlas and axis and the ulna and radius
Hinge joints (synoval joints)
A rounded or convex process of one bones that fits into a concave suface or grove of another bone to allow movement in one plane, usally flexion of extension.
EX: KNEE joint or Elbow joint
Plane (gliding) joints
Articular surface is usually flat or slightily curved. Allows movement in one or two planes (side to side or back and fourth)
EX: intercarpal, intertarsal joints, sternum and clavical, scapula and clavical, superior and inferior articular facets of verebrae.
Synoval joints (diarthroses)
Free moveable joints
two bones united by a bridge or plate of hyaline cartilage. Found between the ribs, sternum (costal cartilage) also piphyseal plates of long bones.
a broad flat disc of fibrocartilage connecting two bones together. Found between two pubic bones and between verebral bones.
